[LG Optimus G (International)] erycx:
I own a F180L and I want to make it E975. I found a tutorial posted by user iEthos:

IF YOU HAVE WINDOWS VISTA OR HIGHER , INSTALL ALL PROGRAMS AS ADMINISTRATOR !!!

1) Download the latest KDZ https://www.wetransfer.com/downloads...5000223/dfc1c4 ( U ALREADY HAVE IT I PRESUME )

2) Make sure you have LG United Drivers already installed (HOPE U HAVE IT

3) Download LG KDZ Updater and unzip it and Install msxml.msi (MSXML 4.0 SP3 Parser)

4) Download the manual adb wipe batch file and unzip it

(U DONT NEED TO DO IT BUT IF U WANT DO IT ..)

NOW RUN WINDOWS ENABLER ( WITH RUN AS ADMIN )

5) Put your Optimus G into "Download Mode" by switching it off, attaching the usb cable to the phone,

holding both the up and down volume buttons at the same time and lastly inserting the usb cable

into the computer; wait for the drivers to finish loading if doing it for the first time.

6) Unzip the downloaded updater zip file and run KDZ_FW_UPD.exe and run (Win Vistsa -> ADMINISTRATOR)

Use these settings;

•Type: 3GQCT

•Phone Mode: DIAG (TRY EVEN CS EMERG.)

•KDZ file: navigate to the folder which you have saved the downloaded KDZ from the step (1)

•Click Launch Software Update and wait for the flash process to finish

7) Your LG Optimus G will restart itself when IParam = 90 is displayed and proceed slower until you

see IParam=1 again (which signals the end of flash, you can safely exit the program then and remove

the cable from the phone). If phone boots up normally, congrats, skip the steps below and proceed

to use the phone as per normal.

DO ALWAYS A HARD RESET AFTER THE FLASH !!!

----------------------------------------------------------------------------------------------------------------------------------------------

However, this most probably will not be the case for newer Optimus-es, as the data partition somehow

wasn’t wiped even when KDZ-ed, remaining ‘dirty’, thus causing bootloop or security infringement.

8) If the phone is stuck at the booting up LG/Telco logo, you will need to manually wipe the data partition.

9) Force the phone off by holding the power button for appx 15secs.

10)Put the LG Optimus G into "Recovery Mode" by holding the volume up and home button concurrently, then

press the power button. Let go of all the buttons after you see the LG logo on screen for the 2nd time

and the screen goes blank thereafter (backlight may still be on). The phone will kind of reboot and then

enters recovery mode. Repeat the process if you did not get it the first time.

11)With the phone in Recovery Mode, connect it to the computer, wait for the drivers to load (if doing it for

the first time), unzip the wipe batch file downloaded earlier from step (4), double click on wipe.bat to

execute the wipe command.

12)Your LG Optimus G will auto reboot when wiped and (hopefully) boot as per normal.

13) Root your mobile : http://www.sendspace.com/file/p8glss

1. Unzip the zip file

2. Make sure USB Debugging is on, and your are in Charge only Mode

3. Run the CurrentRoot.bat, wait for the prompt

4. Change to MTP mode.

5. Wait for your computer to ask how to view files.

6. Press enter in the CMD prompt to continue.

7. Done.

14) Baseband your F180L !!! http://www.sendspace.com/file/u2bpnu

First: After root, Enable USB Debugging, Download this file:https://www.dropbox.com/s/e8vses1vqz...eBandF180L.rar

2. Copy this baseband.img to Internal Storage (/sdcard)

3. Run file flash_baseband.bat

4. Follow the guild.

5. Your phone will reboot and finish!

My question is: did anyone do this? and it worked? And I wanna know, at step 14, when I have to run flash_baseband.bat how should the phone be connected to pc, in download mode or in MTP mode?
